           Summary: Indeterministic lockup on x86_64 with -m32
           Product: Ghostscript
           Version: HEAD
          Platform: Macintosh
        OS/Version: MacOS X
            Status: NEW
          Severity: normal
          Priority: P4
         Component: General
        AssignedTo: support at artifex.com
        ReportedBy: marcos.woehrmann at artifex.com

I've been experimenting with differences in output on the various artifex computers and have 
discovered an indeterministic lockup when compiling ghostscript with -m32 on a x86_64 machine.  

The most reproducible combination of machine, file, and command line I've been able to find is on 
Alex's i7a machine where this command line locks up about 10% of the time:

/home/marcos/nightly_32/gs/bin/gs -sOutputFile=176-01.ps.ppmraw.300.1 -dMaxBitmap=10000 -
sDEVICE=ppmraw -r300 -q -dNOPAUSE -dBATCH -K1000000 -dNOOUTERSAVE -dJOBSERVER -c false 
0 startjob pop -f - < /home/marcos/nightly_32/testfiles/176-01.ps

Note that configure is run with --disable-cups and then the Makefile is modified by adding -m32 to 
CC=gcc (i.e. "CC=gcc -m32").
